TECHNICAL FIELD

The embodiments of the present disclosure relates to the field ofcommunications, and more particularly, to an information sending method,an information receiving method, an apparatus and a system.

BACKGROUND

In systems of Long-Term Evolution (LTE), the time-frequency resourcesused in the uplink and downlink include several subcarriers in thefrequency domain, and the subcarrier spacing of each subcarrier is fixedat 15 kHZ.

In order to flexibly meet the transmission needs of different services,a configurable subcarrier spacing is introduced in the 5th generationmobile communication (5G) technology. The 5G system is also known as newradio (NR) system. The configurable subcarrier spacing refers to aflexible configuration of time-frequency resource blocks with differentsubcarrier spacings instead of time-frequency resource blocks with fixedsubcarrier spacings; for example, a frequency-domain bandwidth isdivided into a time-frequency resource block with a subcarrier spacingof 15 kHZ, a time-frequency resource block with a subcarrier spacing of30 kHZ and a time-frequency resource block with a subcarrier spacing of60 kHZ.

When an access network device sends data to a terminal, it is allowed touse at least two subcarriers with different subcarrier spacings toperform parallel transmission, which requires the terminal to have acapability of parallel processing on signals transmitted by thesubcarriers with different subcarrier spacings. However, since thesystem maximum bandwidth and peak rate in the 5G system are greatlyimproved compared with the LTE system, it will dramatically increasecosts of the design of terminals if software and hardware capabilitiesof the terminals are designed to satisfy the system maximum bandwidthand peak rate. Therefore, different terminals in 5G systems in thefuture may have different capabilities of software and hardware, thatis, the parallel processing capabilities of different terminals aredifferent. However, the uplink/downlink transmission schedule technologyin LTE is performed on the hypothesis that terminals are able to satisfythe system maximum bandwidth and peak rate, and is inapplicable to the5G system in the future.

FIG. 3 illustrates a flow chart of an information sending methodprovided by an embodiment of the present disclosure. In the embodiment,it is illustrated that the information sending method is used in themobile communication system shown in FIG. 1. The method includes thefollowing steps.

In step 301, a terminal generates UE capability information, the UEcapability information being used for indicating a parallel processingcapability of the terminal for signals sent and/or received by at leasttwo subcarriers with different subcarrier spacings, and/or used forindicating a data buffer capability of the terminal.

When adopting at least two subcarriers with different subcarrierspacings to send and/or receive signals, there are two implementationschemes for the terminal.

In the first implementation scheme, the signals sent and/or received byat least two subcarriers with different subcarrier spacings areprocessed in parallel.

A plurality of Inverse Fast Fourier Transform (IFFT) units and/or FastFourier Transform (FFT) units are pre-set in the terminal.

When adopting at least two subcarriers with different subcarrierspacings to send uplink data in parallel, the terminal uses theplurality of IFFT units to modulate in parallel; and when adopting atleast two subcarriers with different subcarrier spacings to receivedownlink data in parallel, the terminal uses the plurality of FFT unitsto demodulate in parallel.

The IFFT units and/or FFT units may be implemented by software, or maybe implemented by hardware circuit. When the IFFT units and/or FFT unitsare implemented by software, the number and computing capability of theIFFT units and/or the FFT units in the terminal are dynamicallyvariable; and when the IFFT units and/or FFT units are implemented byhardware circuit, the number and computing capability of the IFFT unitsand/or the FFT units in the terminal are generally fixed.

Optionally, the terminal generates UE capability information accordingto its parallel computing capability.

In the second implementation scheme, after caching the signals sentand/or received by at least two subcarriers with different subcarrierspacings, the terminal performs serial processing.

A soft buffer is provided in the terminal. When the terminal receivesdownlink data sent by at least two subcarriers with different subcarrierspacings in parallel, at least two uplink data are cached in the softbuffer and demodulated in turn in a serial manner; or, the terminalcaches at least two uplink data to be sent in the soft buffer, and aftermodulating them in turn in a serial manner, sends them in parallel tothe access network device using at least two subcarriers with differentsubcarrier spacings.

Optionally, the terminal generates the UE capability informationaccording to its data buffer capability. The data buffer capabilityrefers to the capability of caching the signals sent and/or received byat least two subcarriers with different subcarrier spacings.

In step 302, the terminal sends the UE capability information to anaccess network device.

Optionally, the terminal voluntarily sends the UE capability informationto the access network device at a pre-agreed timing. For example, theterminal voluntarily reports the UE capability information to the accessnetwork device during a first attach process; or the terminalvoluntarily reports the UE capability information to the access networkdevice when the number of the FFT units implemented by softwareincreases/decreases.

Optionally, the terminal sends the UE capability information to theaccess network device after it receives a UE Capability Enquiry sent bythe access network device. For example, during the process of attach orTracking Area Update (TAU), the access network device sends a UEcapability enquiry to the terminal, and then the terminal reports the UEcapability information to the access network device.

In step 303, the access network device receives the UE capabilityinformation sent by the terminal.

Optionally, the access network device schedules uplink/downlinktransmission of the terminal according to the UE capability information.

Optionally, the access network device schedules uplink/downlinktransmission of the terminal within the capability scope indicated bythe UE capability information. Optionally, the uplink transmissionand/or downlink transmission refers to parallel transmission implementedby at least two subcarriers with different subcarrier spacings.

In conclusion, in the information sending method provided by the presentdisclosure, the terminal reports the UE capability information to theaccess network device, and the access network device can learn aprocessing capability of the terminal for signals sent and/or receivedby the subcarriers having different subcarrier spacings and thenschedules the uplink/downlink transmission of the terminal according tothe actual processing capability of the terminal, so that the accessnetwork device can dynamically schedule the uplink/downlink transmissionof the terminal according to different UE capabilities.

When measuring the capability of the terminals for processing thesignals sent and/or received in parallel by at least two subcarrierswith different subcarrier spacings, the UE capability information may berepresented by at least three different manners. In the embodiments asbelow, FIG. 4 is taken as an example of the first representation manner;FIG. 5 is taken as an example of the second representation manner; andFIG. 6 is taken as an example of the second representation manner.

FIG. 4 illustrates a flow chart of an information sending methodprovided by another embodiment of the present disclosure. As shown inFIG. 4, the present embodiment is illustrated by taking the informationsending method used in the mobile communication system shown in FIG. 2as an example. The method includes the following steps.

In step 401, an access network device sends a UE capability enquiry to aterminal.

Optionally, during the process of attach or TAU of the terminal, theaccess network device sends a UE capability enquiry to the terminal viaa Radio Resource Control (RRC) signaling or a Medium Access Control(MAC) signaling.

Optionally, the access network device sends a UE capability enquiry tothe terminal via a RRC signaling or a MAC signaling before uplinkscheduling or downlink scheduling.

In step 402, the terminal receives the UE capability enquiry sent by theaccess network device.

In the present embodiment, the timing of the access network devicesending the UE capability enquiry to the terminal is not limited. Inaddition, if the terminal voluntarily reports the UE capability enquiryto the access network device, then step 401 and step 402 are skipped.

In step 403, the terminal generates UE capability information includinga parallel computation capability information of Fast Fourier Transform(FFT) and/or Inverse Fast Fourier Transform (IFFT).

Since the signals carried by a plurality of subcarriers require to usethe Orthogonal Frequency-Division Multiplexing (OFDM) technology, andparallel processing capability of the OFDM mainly depends on thecomputation capability of FFT and/or IFFT, the terminal may use theparallel computation capability information of the FFT units and/or theIFFT units to represent its capability of processing the signals carriedby the plurality of subcarriers.

Optionally, the parallel computation capability information of the FFTunits and/or IFFT units may be represented by the number of units andtransformation point number of each unit. For example, four FFT unitsare set in the terminal, and each FFT unit is used to compute discreteFourier transform of 1024 points, then the UE capability information isgenerated according to (4, 1024); for another example, two FFT units areset in the terminal, and each FFT unit is used to compute discreteFourier transform of 2048 points, then the UE capability information isgenerated according to (2, 2048).

Optionally, “the number of units and transformation point number of eachunit” in the present embodiment refers to the unit number of all the FFTunits and transformation point number of each FFT unit in the terminal,and/or the number of all the IFFT units and transformation point numberof each IFFT unit in the terminal.

In step 404, the terminal sends the UE capability information to theaccess network device.

Optionally, the terminal sends the UE capability information to theaccess network device via a RRC signaling or a MAC signaling.

In step 405, the access network device receives the UE capabilityinformation sent by the terminal.

Optionally, the access network device receives the UE capabilityinformation via a RRC signaling or a MAC signaling.

In step 406, the access network device schedules uplink transmissionand/or downlink transmission of the terminal according to the UEcapability information.

For example, the UE capability information is used to indicate that fourFFT units are set in the terminal, and each FFT unit is used to computediscrete Fourier transform of 1024 points, then the access networkdevice schedules at most 4 subcarriers with different subcarrierspacings for the terminal to receive downlink data in parallel, and thedownlink data carried by each subcarrier does not beyond the computingcapability of the FFT unit of 1024 points.

For another example, the UE capability information is used to indicatethat two FFT units are set in the terminal, and each FFT unit is used tocompute discrete Fourier transform of 2048 points, then the accessnetwork device schedules at most 2 subcarriers with different subcarrierspacings for the terminal to send downlink data in parallel, and thedownlink data carried by each subcarrier does not beyond the computingcapability of the FFT unit of 2048 points.

In conclusion, in the information sending method provided by the presentembodiment, through adopting the number of units and transformationpoint number of each unit of the FFT units and/or IFFT units torepresent the capability of the terminal for processing the signalscarried by at least two subcarriers with different subcarrier spacingsin parallel, the access network device can learn the parallel processingcapability of the terminal for signals sent and/or received by thesubcarriers having different subcarrier spacings and then schedules theuplink/downlink transmission of the terminal according to the actualprocessing capability of the terminal, so that the access network devicecan dynamically schedule the uplink/downlink transmission of theterminal according to different UE capabilities.

In the optional embodiment based on the FIG. 4, the terminal may besending uplink data, and a part of the IFFT units are in a state ofbeing occupied; or, the terminal may be receiving downlink data, and apart of the FFT units are in a state of being occupied. At this time,the terminal generates the UE capability information according to theparallel computation capability of the current remaining FFT unitsand/or IFFT units, and step 403 a may be implemented instead of the step403 described above, which is shown as FIG. 5.

In step 403 a, the terminal generates the UE capability informationwhich includes: the computation capability information of currentremaining parallel FFT units and/or IFFT units.

Optionally, the parallel computation capability of the current remainingFFT units and/or IFFT units may be represented by the number of unitsand transformation point number of each unit. For example, four FFTunits are set in the terminal, each FFT unit is used to compute discreteFourier transform of 1024 points, and currently two FFT units are in astate of being occupied, then the UE capability information is generatedaccording to (4−2=2, 1024).

For another example, two FFT units are set in the terminal, each FFTunit is used to compute discrete Fourier transform of 2048 points, andcurrently one FFT unit is in a state of being occupied, then the UEcapability information is generated according to (1, 2048).

Optionally, the unit number of the current remaining FFT units=the unitnumber of all FFT units−the number of FFT units in the state of beingoccupied; and the unit number of the current remaining IFFT units=theunit number of all IFFT units−the number of IFFT units in the state ofbeing occupied.

For example, the access network device has scheduled a first subcarrierand a second subcarrier to receive downlink data for the terminal, whenit is required to schedule a third subcarrier to receive downlink datafor the terminal, the access network device enquires about the unitnumber and transformation point number of the current remaining FFTunits, and schedules downlink transmission for the terminal according tothe unit number and transformation point number of the current remainingFFT units.

It should be noted that when the access network device needs to enquirethe terminal about the current remaining parallel computing capability,the UE capability enquiry sent by the access network device to theterminal may be the same as the UE capability enquiry in the step 401,or may be different from the UE capability enquiry in the step 401, andthe embodiment of the present disclosure is not limited thereto.

FIG. 6 illustrates a flow chart of an information sending methodprovided by another embodiment of the present disclosure. As shown inFIG. 6, the present embodiment is illustrated by taking the informationsending method used in the mobile communication system shown in FIG. 1as an example. The method includes the following steps.

In step 602, the terminal receives the UE capability enquiry sent by theaccess network device.

In the present embodiment, the timing of the access network devicesending the UE capability enquiry to the terminal is not limited. Inaddition, if the terminal voluntarily reports the UE capability enquiryto the access network device, then step 601 and step 602 are skipped.

In step 603, the terminal generates UE capability information, the UEcapability information including: data buffer capability information.

Optionally, a soft buffer is set in the terminal, and the soft buffer isused to cache the signals carried by at least two subcarriers withdifferent subcarrier spacings. When the soft buffer has a large storagecapacity, the terminal caches a plurality of uplink data, and thenperforms processing on the plurality of uplink data in a serial manner;or the terminal caches the plurality of downlink data received inparallel, and then performs processing on the plurality of downlink datain a serial manner.

Optionally, the terminal sends the UE capability information to theaccess network device via RRC signaling or MAC signaling.

In step 605, the access network device receives the UE capabilityinformation sent by the terminal.

Optionally, the access network device receives the UE capabilityinformation via a RRC signaling or a MAC signaling.

In step 606, the access network device schedules uplink/downlinktransmission of the terminal according to the UE capability information.

For example, the UE capability information is used to indicate that thedata buffer capability of the terminal is 4*X bits, then the accessnetwork device schedules at most 4 subcarriers with different subcarrierspacings for the terminal to receive downlink data at the same time.

For example, the UE capability information is used to indicate that thedata buffer capability of the terminal is 2*X bits, then the accessnetwork device schedules at most four subcarriers with differentsubcarrier spacings for the terminal to send uplink data at the sametime.

In an optional embodiment based on FIG. 6, the terminal may be sendinguplink data, and a part of soft buffer is in a state of being occupied;or, the terminal may be receiving downlink data, and a part of softbuffer is in a state of being occupied.
